Write the water balance to express \(Q(t)\), the total discharge at time t, as a function of \(Q_{gw}(t)\), the groundwater exfiltration and \(Q_{gl}(t)\), the glacier melt contribution (we neglect rain and evapotranspiration)
\(Q(t) = Q_{gw}(t) + Q_{gl}(t)\)
Write the solute mass balance to express \(Q(t) EC(t)\) (the mass of solutes exiting the catchment per second) as a function of \(Q_{gw}(t)\), \(Q_{gl}(t)\) as well as \(EC_{gw}\) and \(EC_{gl}\), which are respectively the constant electrical conductivity values for groundwater and glacier melt. EC is a proxy for the concentration of solutes in water.
By substituting \(Q_{gl}(t)\) in one of the previous equations, express \(Q(t)\) as a function of \(Q_{gw}(t)\), \(EC(t)\) and the constants \(EC_{gw}\) and \(EC_{gl}\)
